United States Patent 0 OVERHANGING BRACKET SYSTEM Michel Gabriel Armand Lvigne, Levigne M.G.A., 4 Square des Sablons, Marly-le-Roi, France Filed June 1, 1965, Ser. No. 460,344 Claims priority, application France, June 4, 1964, 976,981 2 Claims. (Cl. 248223) My invention has for its object a method for securing a bracket in an overhanging location and a method for executing such an overhanging bracketsystern.

Hitherto such overhanging supports included an upright fitted to a wall and one or more lbrackets extending horizontally and secured to the upright. Now, the displaying and storing of goods and material in an overhanging position is practically of interest, but its application has been hitherto restricted by reason of the considerable stress produced by the loads acting on the two elements of the support, which stress leads to a deformation and breaking of the uprights in registry with the points at which said uprights are secured to the wall. Therefore, in order to increase the resistance of such supports, it has been necessary hitherto to resort to comparatively thick or reinforced members, which are costly and unaesthetic.

Now, my invention allows securing overhanging brackets in a manner such as will increase considerably the range of applications of such overhanging systems, the points of securing of the brackets to the uprights being practically undeformable while the number of said securing points may be increased as required.

According to my invention, I resort to a right angled upright provided with a row of equally spaced perforations both in its vertical section to be secured to a wall and in its horizontal outwardly projecting section, said perforations being adapted to be engaged respectively by downwardly offset rearwardly directed tenons rigid with the actual bracket and by upwardly directed projections formed by stamping out of the main portion of said bracket, the fitting of said bracket at two points or series of points defined by the double series of perforations in the upright being such that the bracket acts after the manner of a lever. In fact, the weight constituted by its outer overhanging load-carrying portion is balanced by the upwardly directed stress exerted by the tenons on the upper ends of the cooperating perforations which allows the bracket to extend to a substantial distance outwardly beyond the outer end of the horizontal section of the upright under perfectly balanced conditions since the stress exerted by the load on the bracket is transmitted through the lever system constituted by the bracket to the tenons which are urged upwardly against the upper ends of the corresponding perforations. The resistance of such perforations is obviously very large.

In a preferred embodiment, the projections on the bracket are advantageously of a circular stamped out cross-section engaging frictionally the corresponding circular perforations in the horizontal section of the upright while the tenons are square and are fitted in corresponding square perforations formed in the vertical section of the upright. Such an arrangement is illustrated in the accompanying drawings wherein:

FIGS. 1 and 2 are respectively a view from below and a side view of the actual bracket whereas FIG. 3 and FIG. 4 are corresponding views of the upright considered alone,

FIGS. 5 and 6 are views from underneath and from one side of the assembled bracket and upright, a

FIG. 7 is a perspective view from underneath of the same assembly.

In the different figures, the bracket is designated by 1 and the upright by 2. The upright 2, which is to be secured to a wall through any suitable means, includes a vertical section 3 and a horizontal outwardly projecting section 4. The section 3 is provided with a horizontal row of equally spaced rectangular openings or perforations 5 while the horizontal section 4 is provided with a row of circular openings or perforations 6 which row is parallel with the folded edge 7 connecting the two sections of the upright.

The bracket 1 is constituted by a plate extending horizontally to a much greater extent than the horizontal section of the upright and it is provided on the one hand with a downwardly offset rear edge 8 in which are formed through a suitable shaping, a plurality of equally spaced rectangular tenons 9 adapted to be fitted in the corresponding rectangular perforations 5 formed in the vertical section 3 of the upright. On the other hand, there are formed at a point adapted, when the bracket is operatively positioned, to register with the perforations of the horizontal section of the upright, a plurality of stamped, upwardly projecting annular slashes or projections 10 which are adapted to be fitted with a substantial friction inside the perforations 6 formed in the horizontal section 4 of the upright. It is apparent, as already mentioned, that any load applied on the outer portion of the projecting bracket, will be transmitted as an upwardly directed force to the upper edge of the perforations 5 in the vertical section of the upright and is fully absorbed by the latter. This means, of course, that the interconnection between the upper projections 10* on the bracket and the corresponding perforations 6 must ensure a rigid securing, which is actually obtained, as proved in prac tice, by the hard fit between the corresponding parts.

The uniform spacing of the perforations in both sections of the uprights, allows selectively positioning the bracket at different transversely spaced locations.

The uprights and the brackets may be made of any desired rigid material such as metal, wood or plastic material. My improved support may be executed in mass production for pieces of furniture, oflices, stores, warehouses, public works and all private and industrial purposes.

What I claim is:

1. An overhanging bracket system comprising a rightangled bracket including a vertical section provided with a horizontal row of equally spaced perforations and a horizontal section provided with a further row of perforations and a substantially fiat bracket extending in contacting relationship underneath the horizontal section of the upright and the front edge of which projects to a substantial extent beyond the free edge of said horizontal section, said bracket including along its rear edge a plurality of equally spaced downwardly offset tenons to be fitted snugly in corresponding perforations of the vertical section of the upright and upwardly directed stamped out projections adapted to engage with a hard fit correspond ing perforations in the horizontal section of the upright.

2. An overhanging bracket system comprising a rightangled bracket including a vertical section provided with a horizontal row of equally spaced square perforations and a horizontal section provided with a further row of .3 circular perforations, the two rows being parallel and the spacing between the perforations thereof being equal, and a substantially flat bracket extending in contacting relationship underneath the horizontal section of the upright and the front edge of which projects to a substantial extent beyond the free edge of said horizontal section, said bracket including along its rear edge a plurality of equally spaced downwardly offset square tenons to be fitted snugly in correspondig perforations of the vertical section of the upright and upwardly directed circular stamped out projections adapted to engage with a hard References Cited by the Examiner UNITED STATES PATENTS 2,213,115 8/1940 Bales 248243 X 3,051,427 8/ 1962 Alvarez 248224 3,113,353 12/1963 Zell et al. 248 -223 X 3,144,944 8/1964 McConnell 211176 X 10 CHANCELLOR E.
